The debate turned unedifying, with both sides resorting to personal attacks instead of discussing the issues.
Unedifying → It is formed from "un-" (meaning not) and "edifying" (from Latin "aedificare", meaning to build or construct). The word "unedifying" means not building up or improving, often referring to something that does not contribute positively to one's moral or intellectual development.
Think of something that does not 'build up' ('edifying') your knowledge or morals — that's what 'unedifying' means.
